Guarding Drinking Water Safety against Harmful Algal Blooms: Could UV/Cl Treatment Be the Answer?
Environ Sci Technol

Frequent and severe occurrences of harmful algal blooms increasingly threaten human health by the release of microcystins (MCs). Urgent attention is directed toward managing MCs, as evidenced by rising HAB-related do not drink/do not boil advisories due to unsafe MC levels in drinking water. UV/chlorine treatment, in which UV light is applied simultaneously with chlorine, showed early promise for effectively degrading MC-LR to values below the World Health Organization's guideline limits.

The reaction between molybdenum(ii) acetate and 5-aminoisophthalic acid (HIso-NH) afforded [MoO(μ-O)(Iso-NH)], a novel molybdenum(v) metal-organic polyhedron (MOP) with a triangular antiprismatic shape stabilized by intramolecular N-H⋯O hydrogen bonds. The synthesis conditions, particularly the choice of solvent and reaction time, led to the precipitation of the Mo(v)-MOP in five distinct crystalline forms. These forms vary in their packing arrangements, co-crystallized solvent molecules, and counter-cations, with three phases containing dimethylammonium (dma) and the other two containing diethylammonium (dea).

Increasing antimicrobial resistance patterns worldwide have limited the treatment options available. Overuse of carbapenems which were considered as the last resort for multi-drug resistant UTIs over the past decade has led to the emergence of carbapenem-resistant Enterobacterales (CRE).

Article Synopsis
- The study focused on analyzing multidrug-resistant (MDR) isolates for their ability to form biofilms and the presence of associated genes at a hospital in Nepal.
- A significant majority of the isolates were found to be strong biofilm producers, with 195 out of 200 being MDR and 192 capable of biofilm formation.
- Cinnamaldehyde was the most effective compound in inhibiting biofilm formation, with essential oils and Tween 80 also showing high efficacy, providing insights for potential treatment options against these resistant strains.
Experimental and computational kinetic evaluations of silver(I)-catalyzed oxidation of -chlorophenol by hexacyanoferrate(III): exploring the mechanistic pathway.

The present investigation delves into the redox reaction between -chlorophenol (-CP) and hexacyanoferrate(III) [HCF(III)], catalyzed by Ag(I) in an alkaline environment. Findings reveal a first-order dependence on both -CP and the oxidant, and the reaction rate showcased a first-order reaction towards Ag(I), which was further amplified by the medium as per the equation = + [OH]. Interestingly, the ionic strength remained unchanged throughout the reaction, exerting no discernible effect on the reaction rate.
